THILLCQUPLING.

SPECI'FCATION forming part of Letters Patent No. 362.186, dated May 3, 188'?.

Application filed October 1S, 1886.

Z'o all whom t may concern:

Be it known that I, PHILLIP P. SGHAU, a citizen of the United States, residing at Cooper, county of Kalamazoo, State of Michigan, have invented a new and useful Thill-Coupling, of which the following is a specification.

This invent-ion has for its object an iniproved coupling, substantially as below described and claimed, whereby the thill-eye is adjusted in a concave seat by a horizontal gaskward or forward movement of the eye- In the drawings forming apart of this speciiication, Figure l is a side elevation showing the vehicle-axle in cross-section on line l 1 in-Fig. 2, and with the side plate below described removed; Fig. 2, a plan of Fig. 1; Fig. 3, a plan ofthe side plate which bears the clip eye; Fig. 4, a top view of one of the side plates and the eyebolt; Fig. 5, asection on line 2 2in Fig. 6, and Fig. G is a plan of Fig. 5.

Referring to the lettered parts in the drawaXle of a vehicle, and c the clip, which secures the plate D, usually bearing the clipeye, to the axle. The forward portion of the plate D (here shown) has a concave seat adapted to receive the thill-eye a, said seat r o' being open at the front to receive the thilleye a.

Back ofthe seat r1' in Figs. 1 and 2 the plate D is provided with an elongated hole, in which the bolt c is placed. At each end of rations f. The side plates, C, or adjustable drawstraps, properly, have a serrated port1on,f, Figs. 2 and 3, engaging the serrations plate C has an eye to receive the eyebolt s when coupling the thill, and the rear end has a hole, through which the adjusting-bolt e passes, thus attaching the plates or straps O to the plate D. By loosening the nut of the bolt e the straps G can be moved back, causing the eyebolt to be carried back, and by this means causing the eye a to fit closer in the seat r r. By tightening the bolt e again the serrated parts ff engage eachother and hold the plates O from displacement when subjected to the draft-strain in drawing the vehicle. By thus adjusting the thill-eye to take up the wear of said eye and of its seat the bearing is kept .uniform and close, and a successful anti-rattling coupling -is the result, made durable and simple. There are several ways Serial No. 216,503. (No model.)

by which the eyebolt may be carried back in its horizontal position parallel with the axle to adjust the bearings of the thill-eye in its seat.

In Figs. 5 and 6 is shown a plan equivalent, so far as the adjusting is concerned, but for some reasons preferable, to that shown in Figs. 1, 2, and 3.

The rear end of the plate D in Figs. 45 and 6 has lateral projections x x. The draw-rods u take the eyebolt s at the forward end and pass through holes in the projections a; x at the rear end, where they are provided with tightening or adjusting nuts t. In Fig. 5 one of the rods a (anequivaleut to the plate O, Fig. 3) is removed and the eyebolt is in cross-section, as in Fig. 1.

By tightening the nuts t the eyebolt s is carried back, causing a close seating of the thilleye a in the seat i'. One of the rods u may be integral with the eyebolt s, the same as the integral bolts and plate O in Fig. 4. By means ot' this coupling all packings back of the thill-eye or springs to press against t-he thilleye to prevent rattling are dispensed with.

Having thus described by invention, what I claim is*- 1. In a thill or pole coupling, the combination of the eoncaveseat, the thill-eye, the eyebolt, and means for adjnstahly attaching the eyebolt with the vehicle-axle,whereby the l eyebolt may be carried hack in its horizontal position parallel with the axle ,to closely seat the thill-cye in its seat, substantially as set forth.

2. In a thill and pole coupling, the plate having the lateral projection at the rear end on each side, said projections having holes to receive the rear end of the draw-rods,the plates at the forward end being provided with the upwardly and downwardly curved branches, forming a concave seat to receive the thilleye, said plate secured to the axle between the seat and projections, and the draw-rods provided at the forward end with eyes to receive the eyebolt, all combined substantially as set forth.

In testimony of the foregoing' I have hereunto subscribed my name in presence of two witnesses.
